car fridge cooler
Semiconductor car refrigerator Its principle is to rely on the electronic chip cooling, the use of special semiconductor materials constitute the P-N junction, the formation of thermocouple pairs, resulting Peltier effect, that is, through the DC refrigeration a new type of refrigeration. Refrigeration temperature range of 5 to 65 degrees. C This refrigerator has the advantages of both cooling and heating, environmental protection, pollution-free, small size, low cost, no vibration during work, noise, long life. The disadvantage is that the cooling efficiency is not high, the refrigeration temperature is affected by the ambient temperature, refrigeration can not reach below zero, and the capacity is small. Compressor car refrigerator The compressor is the traditional technology of the traditional refrigerator, refrigeration temperature is low, -18 degrees 10 degrees. High refrigeration efficiency, can make ice, fresh, large size, is the future development of the mainstream car refrigerator direction. However, this refrigerator heavier weight, inconvenient to carry, higher prices. car fridge cooler for automobile refrigerators The world's major producers are Germany and Japan.
